Answer 1

Problem:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

Solution:

sudo service mysql start

Answer 2

I solved it by stopping the apache server first and restarting the mysql server

1. sudo service apache2 stop
2. sudo service mysql stop
3. sudo service mysql start
4. sudo service apache2 start

Answer 3

Make sure that Mysql is installed, still able to reproduce the issue, Look for the file in sql/my.cnf file.

Verify that the Socket connection path in that file:

• Location shown in the error is: /var/run/mysqld/mysqld.sock

• Actually location in my.conf file : /home/user/mysql/tmp/mysqld.sock

  home/sql/bin >> mysql -u root -p --socket=/home/user/mysql/tmp/mysqld.sock

In some version's you may find 'mysql.sock' instead 'mysqld.sock'

Hope this can help you (Env: docker ubuntu16.04 container):

i run this code each time restart mysql server, it work for me:

  sudo chown -R mysql:mysql /var/lib/mysql /var/run/mysqld
  sudo service mysql start

Answer 5

I know it's too late, but I had same problem today. It solved by removing current mysql and reinstalling mariadb. It worked for me.

sudo apt install mariadb-server
